Wireless power transfer technologies have been extensively researched for several decades and successfully deployed on a commercial scale. As studies on wireless power transfer technologies have progressed and its feasibility has been tested, electromagnetic radiated emissions have become more important subject than before. In this paper, we report the measurement and analysis of the electromagnetic...
In this paper, we address the problem of choosing the right topology for a wireless power transfer (WPT) application to obtain maximum power transfer efficiency. We analyze the series and parallel resonant topologies used in inductively coupled links, derive the efficiency expressions and verify them experimentally using planar inductors built on a PCB. We compare and contrast the two topologies and...
This study presents a high efficiency inductive power link aiming for the implanted biomedical devices. Improving the efficiency of the inductive link is critical, since the overall efficiency of a remote powering system is dominated by the inductive link. Therefore, the proposed system utilizes the resonance phenomenon which enables maximum energy transfer between objects which are at resonance....
